title: [Mesenchymal extra-skeletal chondrosarcoma. Apropos of a case].
abstract: The authors report a case of extra-skeletal mesenchymal chondrosarcoma in a 22 year old man. This rare tumour developed along the nerve tracts (nerve roots, sciatic nerve and gluteal nerves) with contiguous involvement of muscles and three different bones (vertebra, sacrum, iliac bone). The nature of the tumour could only be determined by histological examination of a large fragment.
